Activity overview:

I show three different methods for subtracting mixed numbers (when we can't just simply subtract the whole-number parts and fractional parts separately):
1. Renaming or borrowing
2. Subtracting in parts
3. Using a negative fraction.

The fractional parts have the same denominator (like fractions), which is the easier situation. It is more complicated if they are unlike fractions - dealt with in another video.
